FINESTRA vol.1

Why Finestra? It is the Italian word for window, which allows light to come in. The camera's aperture does the same thing. By some accounts the "F" in "F-stop" comes from finestra.

The aperture controls how much light gets into the camera to create the image; it also controls how much of said image will be in focus; we call this depth of field. As we look at photos our eyes are instinctively drawn to what is brightest and/or what is in focus; so the photographer controls what the viewer will look at first by controlling the depth of field in the photo!

Try it. As you look at photos, make a mental note of what you noticed first.
